# Exercise 12.7
# 
# Using Bioperl modules mixed with your own code, write a program that runs 
# BLAST on a set of DNA sequences and saves the IDs of the list of hits of each 
# BLAST run sorted in arrays. Allow the user to view each list, to view hits in com-
# mon between multiple lists and hits unique to one of multiple lists. For each hit, 
# enable the user to fetch its entire GenBank record.
#
# Answer to Exercise 12.7
#
# I'm going to leave this one to you.  It is an extension of previous exercises and
# examples.  Your program must extract the list of hits of each BLAST run, and then
# interactively allow the user to see the hits for each sequence.  The user must
# also be able to ask for an intersection of all the arrays of hits, and to find
# hits that only appear in one array of hits.  Finally, you'll need to consult the
# Bioperl documentation to learn how to retrieve a GenBank record, given the ID number.
